Stress relief takes place along fractures, faults, joints and other primary or secondary surfaces in rocks. This destressing may not cause tremors to be felt by anyone located there. However, sensitive seismic instrumental network may record or fail to record them as micro-seism. However, by careful geological observations for micro-relief features along drainage lines, movements along s-surfaces in rocks one can at least know about presence of such activities in the area. I feel many of the slope failures in spite of remedial measures and landslides are caused by tectonic creep. Ignoring tectonic creep can have serious post construction failures along the layout of hydropower structures.
